It's hard to quantify, but as someone who grew up in the south and left, the "unappeal" is definitely apart of the calculus.

Not only do the outdoor activities pale in comparison to what you get in other parts of the country, but additionally so much of the political rhetoric, attitude, and actions isn't just "I want myself, my family, and my neighbors to do well" but "I want other people to suffer."

It's truly a terrible micro-society within the U.S.

Like anywhere, there are of course tons of nice/great people and some nice places. But exceptions, rules, etc.
